| Abstract: | Experiments were conducted to study the effects different fertilization rate on the yields of sunflower growing in saline and alkali soil and to establish a functional equation of fertilizer efficiency.The results show that for the alkali soil: if nitrogen reached 10.56 kg/667m2,the production reached the maximum 183.2 kg/667m2;and if the phosphorus reached 5.71 kg/667m2,the production reached the maximum 156.9 kg/667m2;and for the saline soil: if nitrogen reached 10.51 kg/667m2,the production reached the m... |
